Rat Race Adventure Sports, based in York, organised the event, which centred around Roald Dahl Plass near the Wales Millennium Centre and took runners around Cardiff Bay and to Penarth, before the run back.

One of the obstacles

The weather was bright and sunny as the droves of competitors took on the challenge.

Obstacles ranged from tricky to extremely challenging

Organisers crammed 50 gruelling obstacles into Sunday’s 10k route and they ranged from the tricky to the extremely challenging.

Thousands joined in

Wearing bright yellow kits, competitors climbed over bales of hay, swung from monkey bar rings and had a chance to show their brawn and determination.

Cardiff’s race, which began at 10am, was labelled “wet ’n’ wild” as it involved obstacles with the potential for taking a dunk in rapids.

'All were survivors'

But it was also about team work. Teammates climbed on one another’s backs and hoisted each other up to scale walls and overcome major obstacles on the field.

Teamwork was the name of the game

Last year’s record stands at one hour, one minute and 15 seconds, but all competitors were hailed “survivors” for just crossing the finish line.

Cardiff’s event kicked off a Survival series, which next goes to Nottingham, Edinburgh, Manchester and London.

Up and over!

Once the event was finished, and all the survivors had the chance to head over to the beer tent at the finish line for a celebratory pint.
